2.0 General Description

The LTM-Series are 2-wire electronic field instruments, suitable for installation in hazardous and non-hazardous locations. Testing and certification has been obtained from different agencies for installation in such areas. This instrument is designed to measure and transmit an analog and/or digital signal proportional to liquid level in a tank. The complete assembly includes an explosion-proof enclosure and attached sensor tube and a magnetic float. The LTM-Series are available in a variety of lengths and wetted materials to accommodate many different applications.

Figure 1. Example label/name plate

The product can be identified by the stainless steel label that is located on the side of the transmitter enclosure/housing.

The label can be read as follows:

wwww= Any hazardous location area classification markings that the instrument is approved for.

ZZ/ZZ = Born on date; the2 digit month and 2 digit year the instrument was shipped to the customer.

AAAA= The specific serial number assigned by Magtech for complete traceability.

BBBB= The overall probe length of the instrument. Note: THIS IS NOT THE MEASURING RANGE.

XXXX= The measuring range of the instrument. The 0 and 100% (4/20mA) output range.

YYYY= The end user specified tag number (only when specified).

2.2 Transmitter Configurations

LTM-Series transmitters generally have two configurations:

1.Gage Mounted: Where the transmitter is mounted on the outside of a magnetic level gage and strategically located within a certain longitudinal distance from the transmitter sensor probe and a magnetic float is placed inside the level gage.

2.Standalone (or Direction Insertion Type): Where the transmitter has a magnetic float directly around the transmitter sensor probe and the probe is directly inserted into a tank/vessel.

In either configuration as the tank level changes, the float tracks the change and continuously activates the sensor probe. The electronics process the change in signal and output an analog and/or digital signal. This output is precisely the liquid level in the tank.

Magtech is always willing to explore unique applications that require their own distinctive configurations. Please consult the factory for guidance.
